F. H. BEA CH PUNCHING BAG AFPARATUS Filed NOV. 8, 1934 INVENTOR redercl ZZBeach BY g4;

' ATTORNEY Patented July 23, 1935 UNETED STATES "P TEN. oFFIcE I he invention relates to improvements in punching bag apparatus generally and more particularly to a floor standard support for punch-5.

and packing for shipment or storage.

With this and other objects of equal importance in view, the invention resides in the certain new and useful combination, construction and arrangement of parts as will be hereinafter more fully described, set forth in the appended claim, and illustrated in the accompanying drawing, in

which:--

Figure l is a perspective View of the apparatus in assembly,

Figure 2 is a vertical section through the base structure per se thereof, and.

Figure 3 is an enlarged sectional detail of the top end of the bag supporting standard.

Referring to the drawing, wherein like characters of reference designate corresponding parts in the several views thereof, the embodiment of the invention, as is exemplified therein, is comprised generally in a base It]; a resilient socket member I I posited at the center of the upper side of the base I0; a substantially rigid standard or rod I2 rising from the resilient socket member I I and a punching bag I3 detachably secured to the upper end of the standard I2.

As shown, the base I0 is preferably in the form of a pair of crossed flat members, such as equal lengths of board lumber or the like, which, at their points of crossing, are preferably mortised together so as to lie in the same plane and to firmly rest upon a fioor or other supporting surface. The opposite ends of these crossed members II! may have friction buttons or pads I4, preferably of rubber, mounted on the under sides thereof to restrain the base ill from displacement from set position during punching exercise with the bag I3.

The resilient member II is preferably in the form of an inverted rubber cup, with its lower open side outwardly flanged, as at l5, for centered support on the upper side of the base It and for its securement in place thereon by means of a clamp member I6; the latter being preferably of wood, substantially square in shape, with a centered opening therein to fit down over the resilient socket member and rest upon the top side of the base I6. As shown, the clamp I6 has the edge of the opening therein undercut to snugly engage over the flange I5 of the socket member it when sin-placed in its operative position; I j 1 lihe clamp l 6 is secured to the base In by means of a set of bolts H which are preferably passed upwardly through the base and the clamp to receive winged nuts 58 on the threaded ends thereof. To prevent accidental loosening up of the nuts 28, a washer I9 is preferably emplaced upon each bolt end and between the clamp l6 and a securing nut. The square clamp member it thus provided is positioned over the socket member H and upon the base Ill preferably in a manner that its corners are disposed in the plane of the longitudinal centers of the crossed member Hi, and, by employing but one bolt IT at each of these corner portions thereof for engagement with the underlying portion of .a crossed member, no additional or separate fastenings need be used to secure the crossed members together; it being readily apparent that a rigid assembly of these members andthe member I I will be had when the clamp I6 is secured in place.

The upper closed side of the resilient member H is thickened, as at 20, to form a boss and this is provided with a cylindrical depression which opens through its top end to form a socket for the'reception of the lower end of the standard l2, and, as is shown in Figure 2, it and the engaged. end of the latter are preferably screwthreaded, as at 2!, to provide for a quick setting up or taking down of the standard, as well as to assure that the standard will have firm support in the socket when the punching bag is in use.

The punching bag It is to be detachably secured to the top end of the standard I2, and, to this end, the latter is preferably formed at that end with an enlargement 22 which is to be inserted into the usual laced opening of the outer covering or case A of the punching bag, and to have edges of the opening tightly laced, as at 23, about the standard directly below the same.

To protect the inflation neck I) of the bladder B, housed. within the covering or case A, from otherwise possible injury during the use of the bag, the enlargement 22 of the standard I2 is preferably provided with a cutout portion 24 (Figure 3) to form a recess at one side thereof for its reception, the recess opening through the top side of the enlargement to allow the inflation neck to depend therein, somewhat after the manner shown.

The standard l2 may also have its lower end similarly enlarged, as at 25, with the screwthreads formed in its cylindrical face for engagement in the socket member II. This is particularly desirable when the standard I2 is made from a length of wooden rod, for instance, and it provides for a certain amount of flexing motion to the intermediate portion of the standard, during the punching of the bag, in addition to the springing motion thereof provided for by the resilient nature of the socket member H.

In order to strengthen the socket member H against undue distortion and strain, incident to the springing motion of the standard I2 under the impact of blows delivered to the punching bag, a coiled spring 26 is preferably housed within the member II for the purpose. This spring 26 is preferably of substantially helical form to lend itself to a fit within the member I l in fairly close conformity to the varying curvature of the inner wall thereof.

From the foregoing, it will be entirely obvious that the apparatus thus provided is capable of being made to different sizes and strength of materials, in order to adapt it to use by children as Well as by adults, and that the involved simplicity in design and features of construction permits of its manufacture at extremely low cost, and it will be understood that various changes in form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention, or its scope as claimed.

I claim:

In a device of the class described, the combination with a punching bag, of a standard therefor, a resilient socket member for supporting the standard, a supporting base for the socket member, means for rigidly securing the socket member in place on the base, said socket member being in the form of an inverted rubber cuplike body having its open side secured to the base and a standard'supporting socket formed on the center of its outer wall, and a coil spring housed within the socket member to strengthen it against undue distortion and strain incident to the springing motion of the standard under the impact of blows delivered to the punching bag.
